Check Digit Verification of cas no
The CAS Registry Mumber 2806-97-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,0 and 6 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2806-97:
(6*2)+(5*8)+(4*0)+(3*6)+(2*9)+(1*7)=95
95 % 10 = 5
So 2806-97-5 is a valid CAS Registry Number.

Formation of acetylenic acetals by ring opening of 1,1,2-trihalocyclopropanes under phase-transfer conditions
Sydnes, Leiv K.,Bakstad, Einar
, p. 446 - 453 (2007/10/03)
A number of substituted 1,1-dibromo- and 1,1-dichlorocyclopropanes with an additional chlorine or bromine atom attached to C-2 were synthesized in reasonabk to good yields by dihalocarbene addition to the corresponding alkenes under phase-transfer conditions. When the trihalides were treated with 50% aqueous sodium hydroxide in the presence of ethanol. triethylbenzylammonium chloride and dichloromethane. most of the compounds underwent ring opening and afforded mixtures of acetylenic acetals, usually in good yields. The reaction most likely involves cyclopropene intermediates, which in some cases also rearrange to a minor extent to the corresponding vinylcarbenes and afford α,β-unsaturated aldehydes.
